Eh, it's kinda both. Yes, it's nice to stay on one topic like how we can make communism the best it can be and learn lessons of the past. But when people look at some of those decisions/theories and say "that sounds terrible, I'd rather keep what I have" then you really gotta cross-compare. America is only as well off as it is because of slavery, corruption, death and destruction. It's just not death and destruction of their own people and land, so most American citizens don't "see" that. Or if they do, it's a "well, that sucks, we should do better" kind of thing, but lack real recognition that the system benefits them so much. As well, the capitalist autocracies have been way more deadly and authoritarian and corrupt than anything communist, and it's important for people to learn about the differences.

A: "Communism is authoritarian" B: "Wehll, sometimes, but capitalism is too, and it is MUCH worse" A: "Don't commit whataboutism" B: "Uhhhh, but we have to compare systems to know which is better and which is worse..."

Just IMHO.
